Tutorial 2: A Bottom-Up View of Heat Transfer in Nanomaterials
23 Mar 2011 | | Contributor(s):: Timothy S Fisher
This lecture provides a theoretical development of the transport of thermal energy by conduction in nanomaterials. The physical nature of energy transport by two carriers—electrons and phonons--will be explored from basic principles using a common Landauer framework. Issues including the quantum...

Nanoelectronic Modeling Lecture 23: NEMO1D - Importance of New Boundary Conditions
02 Mar 2010 | | Contributor(s):: Gerhard Klimeck
One of the key insights gained during the NEMO1D project was the development of new boundary conditions that enabled the modeling of realistically extended Resonant Tunneling Diodes (RTDs). The new boundary conditions are based on the partitioning of the device into emitter and collector...

Nanoelectronic Modeling Lecture 24: NEMO1D - Incoherent Scattering
02 Mar 2010 | | Contributor(s):: Gerhard Klimeck
Incoherent processes due to phonons, interface roughness and disorder had been suspected to be the primary source of the valley current of resonant tunneling diodes (RTDs) at the beginning of the NEMO1D project in 1994. The modeling tool NEMO was created at Texas Instruments to fundamentally...
